Abstract:
Provided are a data transmission device, a data reception device, and a data transfer system
capable of surely moving data in the MOVE process of data between a data transmission
device and a data reception device while eliminating the state that data in the
usable state exists in a plurality of devices. The data transmission device (101)
includes a synchronization control unit (405) for synchronizing the timing
of deleting or disabling the data to be moved in the data transmission device (101)
